Download or read book Reducing Soil Water Evaporation with Tillage and Straw Mulching written by S. K. Jalota and published by Wiley-Blackwell. This book was released on 1999-05-12 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: As more and more people compete for ever-less water on our shrinking planet, the problem of soil evaporation becomes increasingly urgent. In this book two of the world's most distinguished specialists in the field offer an expert yet highly readable account of both the problem and potential solutions. Drawing on the work of agronomists, soil scientists, and meteorologists, the authors provide a clear overview of the theories and data that explain the process of evaporation from free water and soils that are bare, tilled, or residue-covered. In a discussion of the benefits of tillage in reducing evaporation, they consider different types of soil and the merits of post drying depth-distribution of soil water in treated and untreated soil. Straw mulching, as another means of reducing evaporation, receives the same extended treatment, followed by an appraisal of the effects of different combinations of tillage and mulching on evaporation and water use during fallow and cropped periods. Addressing a pressing issue in a thorough and objective fashion, this book will assist future decision makers about water conservation management in different climates, under various conditions

Download or read book Mulching in Agroecosystems written by Kashif Akhtar and published by Springer Nature. This book was released on 2022-11-25 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into recent developments in the use of mulching in agroecosystems with emphasis on the major pros and cons. Increase in human population, climatic changes and agricultural intensification have put enormous pressure on soil and water resources. As a result, we are confronted with challenges to enhance nutrient and water use efficiencies and conserve soil organic matter without compromising crop yields and food security. Increasing the soil organic matter (SOM) via residue return increased nutrient availability and soil physical and biological properties. Management practices, such as straw mulching or incorporation, have significant effects on soil health. Straw addition also increases functionality related to carbon and N metabolism via increasing the microbes and thus greatly contributes to CO2 and N2O emissions. However, the co-use of organic and inorganic fertilizer reduces the N2O emission without compromising crop yield. Mulching has long been advocated to conserve soil moisture and increase the efficiency of macro- and micro-nutrients by improving soil physical, chemical, and biological properties. These effects of mulch are translated into better crop yields while improving soil health and quality in the long run. Therefore, the use of mulching techniques is on the rise in organic as well as conventional agriculture. The book is of great interest for researchers, academics, agriculture extensionists, soil and plant scientist, fertilizer industry, farmers, agro-industrial workers, farm managers, NGOs, and climate and civil society activists.

Available in PDF, EPUB and Kindle. Book excerpt: Crop water use can be increased by management of surface runoff, groundwater, irrigation, and soil water. Technological innovations to enhance availability of water for agricultural crops depend on soil and site-specific conditions. Devoted to the principles and practices of enhancing water use efficiency, Soil Water and Agronomic Productivity addresses current problems associated with water supplies required for agricultural purposes and food production. Written for professionals and students in agricultural fields, the book focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. It also presents techniques to conserve water in the root zone as well as remote sensing techniques to assess soil water regime and predict drought on a regional scale. Soil water management is crucial to reducing the vulnerability to agronomic drought. There are numerous examples of aquifers that have been severely depleted by misuse and mismanagement. Soil Water and Agronomic Productivity explains the factors and causes of the mismanagement of soil water and proposes options for sustainable and efficient use of scarce water resources. Meeting the global food demand will require careful worldwide management of soil and water resources, and this can only be done by sharing information and knowledge.
